I'm attempting to deploy an application that uses SQL Server 2005 Express as a back end. I installed the application on 6 or 7 machines, and on two of those machines I'm getting an error message I just don't understand. When I try to connect to the database, I'm getting "System Exception: An invalid IP address was specified.". I'm using the <machine name>\<instance name> to log into the server and I can ping the associated IP address. What's even more confusing is that I can log onto this instance from any of the other machines with no problem. I'm assuming the problem isn't with the SQL instance but a setting I'm missing on the machine, but for the life of me I can't find anything. Any help would be greatly appreciated.

Can you check this blog and see if there is any alias defined on the specific machine?
